Yery local. Mr. Johnson obtained large numbers at Armagh, on 



three occasions — once on Sparganium in September, in a mass of moss 



in May, and in flood-refuse also in May. On other occasions it has 



generally occurred singly. It is always found in marshy places where 



Sparganium and Equisekmi grow, and it is possible that the larva may 



feed on either of these plants. The species is of northern range in 



Great Britain, occurring in various Scotch localities, and as far south 



as Yorkshire. Elsewhere it is found in northern Europe, Siberia, and 



in N'orth America. A variety (var. lapponicus) has been described from 



Lapland.
